Q

what is sensory memory

A

registers info about the environment and holds it for a very brief period of time

Q

sensory memory task: people are shown a screen of letters for 50ms how many can they usually recall

A

between 3-6

12
Q

what does the sensory memory task suggest

A

many items are stored in memory initially
while they are still in memory, observers can attend to some of the items and report them
but they fade away quickly hence why they can only report 3-6

19
Q

what is required for short-term memory to become a long-term memory

20
Q

which items in short-term memory are later remembered?

A

items learned earlier and later tend to be better rememberedd

21
Q

what is long-term memories capacity

A

long-term memory is infinite

22
Q

what can impact long-term memory

A

damage to the medial temporal lobe can cause severe impairment of long-term memory

23
Q

does damage to the medial temporal lobe impact short-term memory

A

no just long-term memory

24
Q

what is needed for working memory

A

central executive

25
what are the types of long-term memory
declarative non-declarative
26
what is declarative memory
memories for facts and events you can explicitly remember these memories
27
what is declarative memory also called
explicit
28
what is non-declarative memory
memories that you cannot explicity retrieve eg. motor skills
29
what is non-declarative memory also called
implicit
30
types of declarative memory
episodic memory semantic memory
31
what is episodic memory
events specific personal experiences from a particular time and place
32
what is semantic memory
facts world knowledge, object knowledge, language knowledge, conceptual priming
33
what part of the brain is associated with all types of declarative memory
medial temporal lobe, middle diencephalon and neocortex
34
types of nondeclarative memory
procedural memory perceptual representation system classical conditioning nonassociative learning
35
what is procedural memory
skills both motor and cognitive
36
what is perceptual representation system
perceptual priming
37
what is classical conditioning
conditioned responses between 2 stimuli
38
what is non-associative learning
habituation and sensitisation
39
what part of the brain is associated with procedural memory
basal ganglia and cerebellum
40
what part of the brain is associated with perceptual representation system
perceptual and association neocortex
41
what part of the brain is associated with classical conditioning
not the brain but the skeletal system
42
what is associated with nonassociative learning
reflex pathways
43
what are the processes of declarative memory
encoding storage retrieval
44
the way info is processed affects how well it is encoded in longterm memory:
depth (levels) of processing
45
does it matter if participants didnt intend to learn
no, incidental and intentional work if it is deep learning
46
what are memory traces associated with
eachother semantic info episodic info
